Abstract: This work reports the design, numerical modeling, and optimization of a new solar water heater using a heat pipe parabolic trough collector (HPPTC) with low concentration ratio. The heat pipe evaporator is positioned on ...

Abstract: In this work, we demonstrate the improvement of thermal performances of a heat pipe parabolic trough solar collector by optimizing the annulus space, between the evaporator and the glass envelope, and using an appropriate ...
